Abstract

PURPOSE:To form gate wiring at low cost in a single mask process by forming a gate electrode of a metal film of at least two-layered structure of metal with high electric conductivity and metal with high anode oxidizing performance. CONSTITUTION:For example, an Al layer 4 of 200Angstrom in thickness and a Ta layer 5 of 2,000Angstrom in thickness are adhered over the entire surface of a glass substrate 1 continuously by sputtering, the surface of the Ta layer 5 at a necessary part is covered with a mask made of a photoresist film, and a gate electrode 2 and gate wiring 3 are formed by etching in the pattern shown in a figure. In this case, the gate wiring of two-layered structure of the Al layer with low electric resistance and the Ta layer 5 is formed by 1st etching using the single mask, so the number of times of mask etching is reduced from conventional twice to once to manufacture the gate wiring with small specific resistance at low cost.
